IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 191,671, dated June 5,1877,- application filed April 21, 1877.

way for foot passengers, and, when a larger opening is required for thepassage of teams, can be swung on its hinge in the ordinary manner.

My invention consists, first, in an improved gate, secured by one of itsupper rails be tween two revolving rollers, one of which is secured to agudgeon mounted upon an arm adapted to move in the arc of a circle upona bracket attached to the gate-post, the lower .rail of said gate beingsecured between two rollers mounted upon gudgeons secured to a movableattachment which rests upon the ground, and which is connected to themovable gudgeon above, the gate being capable of a primary movement in astraight line and a secondary movement in the arc of a circle, as morefully hereinafter set forth; second, in an improved gate-hinge,consisting of a horizontal semicircular bracket adapted to be attachedto the gate-post, and provided with a stationary perpendicular gudgeon,to which is pivoted an arm provided with a similar perpendiculargudgeon, the two gudgeons being provided with friction-rollers betweenwhich the upper rail of the gate is secured, and adapted to travel, asmore fully hereinafter set forth; third, in combination with thestationary gudgeon and the plate to which it is secured, a semicircularrecess, inclining from each end to the center on the quadrant, and asemicircular cam adapted to work in said recess for the purpose ofsteadying the gate while it is being moved in a direct line, as morefully hereinafter set forth; fourth, in the combination, with thegudgeons of the plate and pivoted arm, ofgtwo peculiarly-constructedfriction-rollers, between which the upper rail of the gate is securedand adapted to travel; fifth, in the combination, with the lower rail ofa gate, of a movable attachment which rests upon the ground and isprovided with friction-rollers, between which the lower rail of the gateis secured and adapted to travel; sixth, in the combination, with saidattachment, of an adjustable standard for securing the same to the railof the gate, in ordeii to adapt the attachment to various-sized rai s.

In the drawing, Figure 1 represents a perspective view of the gate in aclosed position; Fig. 2, a similar view of the gate partly open Fig. 3,a detached sectional view of the gatepost and its hinge; Fig. 4., a topview of the gate-post and the hinge; Fig. 5, a detached perspective viewof the gate-post and its hinge; Fig. 6, a vertical sectional view of thelower attachment; Fig. 7, a top view thereof, and Fig. 8 a perspectiveview of the same.

The lettersA A represent the gate-posts, and B the gate, constructed ofthe ordinary horizontal bars, secured to the upright end pieces, asusual. B represents asemicircular plate or quadrant, provided with adownwardly-extending plate, 0, and brace I). Said plate is adapted toset and be secured in a suitable recess formed in the upper part of thefence-post, and serves to firmly support the quadrant in position. Tothe upper side of the quadrant, at the center of the circle of which thequadrant is a part, is located an upright gudgeon, E, to which ispivoted an arm, F, which is adapted to move in the arc of a circle uponthe upper face of the quadrant B. Directly at the base of said gudgeonis formed a semicircular recess, G, which gradually deepens from eachside to the center, and on the lower corresponding portion of the arm Fis formed a semicircular cam, F, which rests in said recess when thegate is fully opened, and serves to hold the same in position. The arm Fat its free end is provided with an upright gudgeon, H, and bothgudgeons E and H are surmounted with friction-rollers I I, having abroad flange at the base. One of the upper rails of the gate is securedand adapted to travel between these rollers, as more fully hereinafterexplained.

The gudgeon H extends above the top of ,its friction-roller, and to suchprojecting portion is pivoted a horizontal plate, J, which is secured tothe upper end of an inclined bar,

the lower end of which is secured to the movable attachment secured tothe lower rail of the gate, which moves with said gate when it is swungon its hinge, and which rests on the ground when the gate is closed.Said attachment consists of a horizontal plate, K, having aperpendicular standard, L, in front, and two perpendicular standards, M,at the rear, to which is adjustably secured a perpendicular standard, N,by means of screw-bolts 0, said standard being provided with ahorizontal extension, P, which embraces the upper edge of the lower railand secures the attachment thereon. To the plate K are secured twoupright gudgeons, R, upon which are mounted friction-rollers S S,similar in construction to the rollers I I of the gate-hinge above de'scribed. The lower rail of the gate is held and adapted to travelbetween these rollers, as more fully hereinafter set forth.

The operation of my improved gate is as follows: The gate being closed,as shown in Fig. 1, in order to open it slightly for footpassengers itis forced back from the gatepost A, traveling between thefriction-rollers I 1 of the hinge and the similar rollers S S of theattachment.

When required to be further opened to admit of the passage of teams, itis forced farther back in the same direction until the rear endcounterbalances the front, when it can be swung in the arc of a circleupon its hinge, the arm F swinging upon the gudgeon E until the gate isfully opened, in which position the cam F will enter and rest in therecess G, steadying and holding the gate in position. To close the gatethis operation is repeatedthat is to say, the gate is first swung backinto position shown in Fig. 2, and then pushed forward to position shownin Fig. 1.

It will be perceived that, as the gate only makes a revolution on thegudgeon E of a quarter of a circle, the hinge is adapted to be usedeither for right or left gates without alteration, which is a matter ofgreat convenience.

Having described my invention, what I claim, and desire to secure byLetters Patent, 18-

1. A gate secured by one of its upper rails between twofriction-rollers, one of which is secured to a gudgeon mounted upon anarm adapted to move in the arc of a circle around the other roller, thegudgeon of which is fixed to a bracket attached to the fence-post, thelower rail of said gate being secured and adapted to travel betweenfriction rollers mounted upon a movable attachment embracing the lowerrail, the whole being constructed and arranged to operate substantiallyas set forth.

2. A gate-hinge consisting of a bracket provided with a horizontalsemicircular plate, having a perpendicular stationary gudgeon, to whichis pivoted an arm capable of a movement in the arc of a circle, which isprovided with a similar perpendicular gudgeon, both gudgeons beingprovided with friction-rollers, between which the upper rail of the gateis secured, the whole adapted to operate substantially as set forth.

3. In combination with the stationary gudgeon and the plate to which itis attached, provided with a semicircular recess inclining from each endto the center, an arm having a semicircular cam pivoted to said gudgeon,adapted to work in said recess, substantially as and for the purposesdescribed.

4. in combination with the gudgeons of the semicircular plate andpivoted arm swinging thereon, the friction-rollers, provided withflanges at their bases, substantially as herein set forth.

5. In combination with the lower rail of the gate, the movableattachment provided with Witnesses PAEVIS WING, G. J. SWAN.
